According to Cincinnati Bengals head coach Marvin Lewis, who leads a weekly Wednesday press conference before the first practice each week, the Cincinnati Bengals could have a full complement of players on the 53-man roster, save for Dre Kirkpatrick.
The players of note are guys whom have missed the entire regular season, specifically defensive end Carlos Dunlap, cornerback Jason Allen and running back Bernard Scott.
Now does that translate to playing on Sunday? Unknown. It's always been a policy of Marvin Lewis' that you must practice during the week heading into a game, with (more times than not) full participation on Friday.
